After a while, soshyan realized that the rest of the aliens had disappeared.

The tunnel suddenly emptied.

Sol, who stepped forward, pierced the alien head that was still struggling on the ground with a bullet, but his whole lower body was torn, and then stood next to soshyan.

"It seems that the alien threat has been fully confirmed."

Hearing Sol's words, soshyan responded with a cough.

They stood in the middle of the piles of corpses. He could hear the heavy breathing of the fighting brothers from the communication and knew that they were struggling to calm their war - astat had to know how to control it when he used his violence.

"Your opinion is to return -"

Before the words fell, they heard a loud noise of explosion and falling stone collision from the channel.

There is no doubt that the tunnel back to the secondary mining area has collapsed, and the enemy has obviously arranged an ambush, or the killing itself is part of the ambush.

These aliens are by no means mindless beasts.

The next situation also confirmed soshyan's idea

From the deeper part of the ore tunnel ahead and from the other two tunnels leading to the intersection, all kinds of guns began to shout and spit.

"Shift right."

Soshyan's concise command turned from the darkness illuminated by the fire and retreated to the light at the intersection.

As they ran, bullets stirred up rubble and blew up chunks of soil from the walls on both sides.

During the operation, soshyan felt a bullet hit heavily on his left shoulder guard, but it was blocked by the outer refined gold.

Another shot exploded when it rubbed against his backpack. It was undoubtedly a bomb gun. The enemy also had heavy bomb weapons.

Then the third shot hit a huge spark on the track under his boots.

More bullets flew into the entrances of the other two adjacent tunnels, and the heavy muzzle fire revealed weak but running red eyes.

"The bird divination instrument fails."

Sol shouted as he hid in the bunker next to him. The filled bucket trembled when the bullet hit its surface and exploded.

"Is there any other route?"

"I'm scanning. Maybe I can, but it will take time."

That said, aliens won't give them time.

The fire from the attackers in the dark was increasing. Even when soshyan's idea was formed, with the scream of launch, there was a crash and a fragment rocket trajectory from the opposite tunnel.

The next second, it crashed into an overturned ore bucket in front of it, tied it into a sieve with fragments and let it fly as a whole.

According to the astat canon, the standard procedure for solving such an ambush is a covered circuitous counterattack, but the narrow terrain limits such operation.

Then there is only one solution.

"We need to attract them to open areas and solve them at one time."

Soshyan said on the public channel:

"We retreat."

"Where? They have blocked the only way back to the secondary mining area."

"There is a transportation channel over there, which will lead them to the intersection."

"According to the scan, there is no shelter."

Sol then warned.

"You have to think about it."

"If we try to be dragged here by them without support, we will only waste time and have more uncertainty."

Soshyan made up his mind.

"Withdraw in combat formation and retreat to the left tunnel."

The star Knights then withdrew from the bunker, while the first half of the tactical team began a protective volley, throwing explosives blindly into the attacked tunnel.

While they did so, the second half of the team got up and kicked up the gravel on the rail sleepers and rushed back to the transportation channel.

When they left, they were attacked. Solid bullets hit pottery steel and bled the weak points of their armor.

But there was no loss of personnel before they entered the darkness of the tunnel.

"Fire cover."

Soshyan then directed the second half of the team to fire and cover the withdrawal of the front team.

The front team was led by sol, who moved with a blaster pistol and fired a series of bullets at the entrance of the nearest tunnel.

He suspected that he had hit anything, but that was not the purpose.

Before escaping into the entrance of the passage, sol threw a grenade back. After a loud noise, there was a wail.

The white burning energy exploded on one wall of the tunnel, which not only aroused a burst of blood fog, but also instantly lit up the attackers - a group of fourth-generation hybrids wearing miner uniforms without a hair on their heads and holding format guns.

They look almost the same as humans, except for their pale skin and appearance, but they are undoubtedly alien and non-human.

Such existence also means that the planet has been infiltrated very seriously.

This brings to mind the unique reproductive pattern of gene thieves.

First, initially, pure gene thieves inject genetic material into the host to open the cycle of infection.

When the parasite spreads out and the stealer sect grows, the first stealer will control the stealer patriarch, and then slowly grow into a huge psionic monster - the nest master.

The boarded will return to their society, and then begin to have an urgent desire to find a partner to form a family, which will later be infected by the stolen gene.

The physical structure of the boarders is still roughly similar to their race, although some are pale and blue, and will be controlled by the patriarch's mind and become slaves, which makes them perfect infiltrators.

Then the lodgers will give birth

The first generation of alien freaks is also the first generation of hybrids

Compared with other gene stealers, the early hybrid is just a group of animals, slow, clumsy and low-energy. The stealer sects often only regard them as consumables.

They usually have three or four arms and do not use the technology and weapons of the host race, but they give birth

Second generation hybrid.

Each second-generation hybrid is unique. This generation can selectively reproduce. Most of them use their parents as livestock, and some characteristics have been strengthened, such as speed, strength and aggression.

They are more like a host race than gene thieves in the conventional sense, but they still can't use the technology of the host race.

Their offspring is the third generation hybrid.

This hybrid has been very close to the appearance of the race they parasitize, and can even blend into the host race. If they wear disguised clothes or hide in the shadow, they can even move in the society of this race.

More importantly, some individuals in this generation have been able to use the weapons of the host race.

They gave birth to the fourth hybrid generation, which is also the generation that is most difficult to distinguish from the host race.

The fourth generation hybrids have only minor deformities, but some individuals still have identity signs, such as bald heads or fangs.

Because they can integrate into the host society, they will try to seduce, kidnap or whatever methods to increase the host as much as possible.

Some rare individuals in this generation will even have psionics, and these individuals will become thieves and elders.

Here comes the most bizarre reproductive part of the gene thief.

Recently, the fourth generation of host like hybrids, their fifth generation, but

Abnormally, it will be "beaten back to its original shape".

In the fifth generation, the DNA of gene stealers will reappear on them, making them complete Talon gene stealers, a terrible alien killer, but with some physiological characteristics of the host race.

The cycle of penetration begins, and a new thief will have the potential to penetrate another world.
